Fully Shielded Cabling
(S/FTP)
Fully shielded cabling requirements have been developed by ISO and
IEC. Cable and connector specifications extend to 600 MHz and support
class F cabling requirements. (An ISO/IEC project has been started
to create amendment 1 of Ed. 2 of ISO/IEC 11801, which extends class
F to 1.0 GHz). This cabling type is recognized as S/FTP, which stands
for a foil and braided overall shield applied over individually
foil shielded twisted-pairs. Fully
Shielded Cable:
Color-coding:
Pair 1 = White/Blue - Blue
Pair 2 = White/Orange - Orange
Pair 3 = White/Green - Green
Pair 4 = White/Brown - Brown
Four 0.51mm (24 AWG) or larger 100 . twisted-pairs each enclosed
by an individual foil shield with an overall shield provided over
the four-pairs.
Mechanical and transmission requirements developed by ISO and
IEC.
Fully Shielded Connectors:
Cabling interface and pair assignments specified by ISO/IEC 11801:2002.
Mechanical and transmission requirements specified in IEC 60603-7-7
and IEC/PAS 61076-3-104.
Fully Shielded Patch Cables:
Mechanical and transmission requirements are specified in IEC
61156-5 and IEC 61156-6.
